Be it known the-"t I, FRANK SCHNEIDER,

a citizen of the United States, residing at Helena, in the county ofLewis and Clark and State of Montana, have invented certain new anduseful Improvements in a Conn 'bined Joining and Fraying Machine, ofwhich the followi-ng'is a specification.

This invention relates -'to an improved joining and fraying machineparticularly adapted for use in the manufacture offlufl rugs. In thepresent manufacture of what are =lrnown as fluff rugs, it is customer Tto utilize old carpets which *have first been cut into strips of variouslengths and then connected by sewing or in any cther suitable manner,providinga continuous strip, which is passed through what is known as afray ing or rave'l'ling machine, which severe the warp threads uponopposite sides of the center of the strip leevingt'he warp threads inthe center of the stripinte-ct. In thiscnethod, only fairly good carpetscan be used, as old or worn carpets will tear apart in the frayer orraveller. I I

It is the main object of my invention to provide a. combined joining andravelling machine, whereby the various lei'igthsof carpetqn'ey be passedthroughthe machine with 't-heends of the strips overlapping one anotherand while the strip is passing through the machine n cord fed uponoppositesides of the strip so that after the strips have passed'throughthe fraying machinennd the inejority of the warp threads out and thenpassed into the twisting machine, the cords which are disposed uponopposite sides of each of the strips will hold the woof threadstogether, and prevent any displacement thereof while passing through thefraying nmchine and also provide for a strengthening of the strip after*being twisted.

Another object of the present invention is the provision of an improvedjoining and fraying rmachine wherein the strips of can pets whichare-cut in various lengths maybe readily fed into the machine with theends in overlapping relation-nnd-thewarp threads upon opposite sides ofthecenter of the strip readily severed at intervals and wherein noextraordinary strain is placed upon "the remaining warp threads whichareleft intact which will lessen "the liability of accidental ripping ortearing of the strips as they are passed through the machine.

A further object of the present "invention "view, taken nism.

is 'the' provision of a combined joining :and

fraying/machine of the above character,

"wherein l the strips of carpet are readily ,iguided between the presserroll and the cutting knlves so that the warp threadswill :be

readily severed to the proper width upon opposite sides of the center ofthe strip and leave a suh'icient numherfiof warp threads in the centerof the :strip to, retain the strip "intact and prevent the same frombeing ripped or torn apart. Q

'Astill further object of the invention is "the provis'ionfof machine ofthischaracter, wherein means is provided" for feeding strengtheningcords to opposite sides of the strip while being fed through themachine,

passes from the fraying machine, ready to be fed into 'thetwistingmachine, any displacement on the part of the woof threads iseliminated".

, IWith thealbove'und other objects in view, the invention consists inthe novel, features of construction, the combination and arresngement ofparts as will be hereinafter more fully set. forth, pointed out in theclaims end shown in the accompanying drawings, in which:

Figure l is a side elevation of my improved oining and ravellingmachine.

Referring now more particularly to the drawings, wherein variousreference characters are used to designate the several parts throughoutthe views, A indicates the frame which. supports my improved machine,said machine including the feeding mechanism B and the cutting andjoining mechanism C, the latter including in its construction the meansfor feeding the strengthening cords to opposite sides of the strip as itis passed through the machine.

The frame A includes in its c0, a supporting table for the feedingmechanism. This table for the feeding. mechaism comprises plurality ofuprights 1, suitably connected by the longitudinal pieces "2 and thetransverse members 3. Mounted upon the top of the frame is a platform 4,which may be utilized for supporting a number of the strips prior tobeing fed into the machine, the ends of said platform being recessed topermit the rota tion of the pulleys 5 and 5 which are mounted upon thetransverse shafts 6, said shafts having their ends mounted within theuprights 1.

The feedingmechanism in general consists of the pulleys 5 and 5 overwhich is passed the belt 7 and mounted upon the belt 7 are the guidetrays 8 which are preferably of a width to accommodate various widths ofstrips which are to be fed into the machine. Attention is directed tothe fact that these trays 8 are loosely connected to the belt 7, so thatthey may readily pass around, the pulleys 5 and 5. In order to carry thestrips into the cutting machine when'being placed within the trays 8, acon veyor belt 9 is arranged within the trays 8, and in order to providefor positive feeding of the strips into the cutting machine, theconveyor belt 9 passes around the guide pulley 10, which is arranged inclose proximity to the cutting mechanism, so as to carry the strips ofmaterial as close to the cutting mechanism as possible in order toinsure the positive feeding of the same thereto.

The guide pulley 10 is supported upon a bracket 11, which is carried bythe frame 8 and is arranged within the transverse open ing formed in thebottom of the guide member 11, whereby it will be noted that when theconveyor belt reaches the forward end of the feeding mechanism, it ispassed around the pulley 10, so as to carry the strips of material asclose to the cutting mechanism as possible, and after passing around thepulley 10 is guided back into the tray members 8;

It will be noted that two of the uprights which comprise the supportingframe for struction the feeding mechanism extend upwardly above theplatform, as shown at 12, and mounted at the upper ends of theseextended portions are suitable bearings 13 in which the ends of theshaft 14a are mounted. This shaft 1st supports the pulley 15 and alsosupports the arms 16 which are loosely mounted upon the shaft andsupport at their outer ends guide pulleys. Both of the pulleys 15 and 17are grooved to receive a belt 18, which passes around the pulleys and isarranged in close proximity to the conveyor belt 9, so that when thestrips of material are fed onto the conveyor belt and toward the cuttingmechanism, the belt 18 will contact with the upper face of the stripsholding the same against longitudinal movement on the belt 9, so thatwhen the strips are fed toward the cutting machine with their ends inoverlapped relation, the belt 18, together with the pulley 17 willretain the ends of the strips in their proper positions when being fedinto the cutting mechanisms. Attention is called to the fact that as thearms 16 are loosely mounted upon the shaft 1%, the weight of the pulley17 tending to bear constantly upon the upper face of the strips ofmaterial will retain the material against movement so that the same willbe fed into the cutting mechanism in its proper position to have thenumber of warp threads out upon opposite sides of the center of thestrip.

The main portion of the frame A supports the cutting mechanism andincludes a platform 19 having upon its upper face the spaced bearingsockets 20 and extending upwardly from these sockets are the threadedsupporting posts ,21. The bearing sockets 20 are connected by means ofthe longitudinal beams- 22, each having the spaced transverse openings23 there-through for the reception of the operating shafts 24-, and 24.li fountcd upon the outer end of the shaft 24 is the drive pulley 25,which is connected by means of a belt 26 to any suitable source of powerwhich may be utilized for driving the machine. The. shaft 24 alsosupports agear 27, which is mounted upon. the shaft and arranged betweenthe pulley and one of the longitudinalbeams as clearly illustrated inFigure 4;. The shaft at has mounted upon one end there of the gear 28.Supported upon the upright post 21 and arranged in spaced relation withthe beams 22 are a second set of beams 29, which are arranged in spacedparallel relation as shown in Figure 4 and each of these beams 29 isprovided with an'opening to receive the threaded post 21, said beamsbeing retained in position above the beams 22 .by means of the nuts 30,which are threaded onto the post 21 and arranged upon opposite sides ofthe beams 29.

The ib am 29 a e p ovided with aligned ameoze p shafts 24, 24- and 33will be driven simultaneously.

Mounted noon the end 01 the shaft/31 opposite the gear 32 is thepressure disc 23, said disc being retained uponwthe end of 't l-ie shaftby having the end of the shaft threaded "and a nut 34 mounted upon thethreaded portion. adapted to be screwed firmly against the face of thedisc to retain the same in position upon the 'end of the shaft.

tact that the endsof the shafts 241 and 2 2" opposite the gears 27 and28 are provided with. reduced portions and 35 and-mounted upon thesereduced portions 35andh35 are the cutting discs 36. These d1scs 36 areprovided upon their zperipheries with the cutting:edges-37 whichare'arra'nged in cirrum'te-rential spaced relation :and are so arrangedWith respect to the vi 33 that during the rotation of :the disc and thedisc 36, the cutting edges-3;? will ('OHSQPlltlVQl) engage the periphery01 :the disc 33. The discs $56 are keyed' to the ends of the shafts 24-.and 2st 2U1ClAlClf lPlE ed. to rhea-l e therewith and are retained inspaced relation by means of a spacing-plate $38. This plate -88 providedwith transverse hearing openings arranged in spaced relation and mountedWithin these hearing openings are the sleeves 39 whichare'looselymounted upon the shafts 2-35 and-35 and atlention is directed to thefact that these hearing sleeves are fitted Within. the openings in theplate -38 so that'the ends of the sleeves $159 will project hevondtheside faces of the plate and engage the faces of the disc 36, to.prevznt frictional contact-helween the plate 38 and the disefio.

iii-ranged upon opposite sides "of eacl pair oi discs 36 are the guideplates 4:0, each oi said guide plates heing, provided with sparedopenings and mounted within heee openings are the hearing sleeves il,ends of which project beyond the side faces of the plates if) so thatthere will he no fllCtiOl'lPll Contact between the discs '36 and theplates 40.

In order to impart pulley 5 located at theforward end-oi the feeding "mechanism and adjacent the cutting mechanismis provided with an extended iface portion over which .a belt '56passes, said =belt extending around a ,pulley if)? mounted upon theouter end of the shaft guide 52 and then upwardly around the fiorivard'end of the plate 38. J-noted that the,'lorwardemlof the plate 38is'providedrwith la ;roove 53 forming a 24: From this it will beapparent that the feeding mechanism is operated simultaneously with thecutting mechanism.

From the above description, it will be readily apparent that after theold carpets have been out into strips of various lengths, they may bereadily placed within the trays 8 upon the conveyor belt 9 with theirends in overlapped relation and through movement of the conveyor beltwill be fed through the guide 11 onto the first set of discs 36, theplate retaining the strip against lateral movement so that when the samepasses between the discs 33 and the first set of discs 36, the propernumber of warp threads will be severed upon opposite sides of the centerof the strip and the rods 38 and d1 threaded through the machine uponopposite sides of the strip. As the strip leaves the first set ofcutting discs, it is guided by the plate l0 between the second set ofcutting discs and the disc 33 so that the side warp threads may befurther out to provide for the separation of the ends of the woofthreads in each strip, leaving only the central warp threads intact. Ina great many instances, these warp 7 threads which remain intact in thecenter are not sufliciently strong to retain the woof threads in theirrespective position, and it is the object of feeding the cords 48 and 51on opposite sides of the strip to retain these woof threads in theirrespective positions and should any of the remaining warp threads becomebroken by passing through the cutting mechanism.

In the construction of my improved machine, it is preferred tohave thedisc 33 formed of comparatively soft material, such as soft steel or thelike, so as to not upset the cutting edges 37 on-the discs 36 whichcontact with the periphery of. the disc 33 and it will be noted fromthis that through constant contact of the cutting edges 37 with theperiphery of the disc 33, a continual wear upon the periphery of thedisc 33 will be carried on through the engagement of the cutting edges37 with the disc. In order to compensate for this wear upon theperiphery of the disc 33, the shaft 31 may be slightly adjusted in avertical plane through the adjustment of the nuts 30 arranged uponopposite sides of the supporting beams 29, which are mounted upon theupright threaded posts 21,- It will be understood that this adjustmentof the shaft 51 is comparatively slight so as not to interfere with thecontinual engagement of the gears 27, 28 and 32. Through thisadjustment, the slight wear upon the periphery of the disc 33 will bewell taken care of, so that the proper amount of pressure between thedisc 33 and the discs 36 will be arranged forso as to positively severthe warp threads along the sides of the Strips by being passed throughthe cutting mecha nism. In Figure .6 I have shown a plan view of thestrip of old carpet wherein the warp threads are intact and the strip isin position to 'be inserted in the cutting mechanism. In Figure 7 a planview of the strip is illustrated, showing the position of the stripafter being passed through the first set of discs 36, illustrating anumber of the warp threads upon the opposite sides of the center of thestrip in severed position and it will be apparent that after this striphas been passed over the second set of cutting discs 36, the remainingportions of the side warp thread will be severed so as to leave the endsof the woof threads entirely separated.

In Figure 8 I have illustrated a plan view of the fluff after the samehas been twisted,

prior to weaving a new rug. In this view, it will be noted that thecords 4:8 and'51 which are arranged upon opposite sides of these stripsare twisted with the strip so that when the strip lies flat, asillustrated in this figure, the cords will be alternately arranged uponopposite faces of the sections 58 of the strip and by having the cordsarranged in this manner, they will be retained in a comparatively tautcondition so as to eliminate any displacement on the part of the woofthreads while the strips are being woven.

By the use of my improved combined joining and ravelling machine,attention is directed to the fact that considerable time and labor isthus saved in forming the strips ready to be woven into what'are knownas flufi' rugs. Heretofore the strips had to be sewed together by handinto a continuous long strip prior to the insertion into the ravellingor cutting machine, and no means has heretofore been provided forreinforcing or strengthening the strip prior to its passage into thetwisting machine, so that considerable material has been wastedheretofore, due to the fact that in a great many instances the carpetsfrom which the strips were out were too old and worn to stand the strainwhile being passed through the ravelling machine, but with my improvedmachine, and method of strengthening or reinforcing the strip, all typesof old carpet or worn carpet may be utilized with very little danger ofthe tearing apart of the strips while being passed through the ma chine.

In the illustrations in Figure 6, attention is called to the fact thatfor the purpose of clearly illustrating the various positions of thewarp and woof threads, the warp threads 59 extend alternately uponopposite sides of the woof threads 60, and the woof threads 60 arespaced at intervals, this space ing usually taking place while the warpthreads 59 are being severed y the Cutt ng ascents and. twistedasshow-min Figure 8, the loose ends of the Woof threads will" form. acoin.- pa'ratirely' fluffy strip which when woven intorugsand the likeform what are known as fluff rugs.

In order to. provide.- for the: proper tension in the feeding of the.strip,.i:t. will be noted that thebelt I8 and pulley lesser-ta pressureupon the upper face of: the strip while heing fed to the cutting machinesor that the strip will be evenly fedi between. thedi'scs 33 and'36,andbyhaving the tension: springs: 5% bearingagainst the-ends of thespoolseo and: 50, the cordst8i and 5'1. will befed onto opposite sides.of: the strip. at an. even. tension, so that when the strip; leaves thecutting machine with the side warp threadssevered, the reinforcingcords4'8: and llrlihlietflllr the wool threads in.- their respectivepositions providing any of the remaining; or ii] tactwarp.threads-become broken, so that they strip may be readily passed'into the twisting machine fiortwisting into the: for-ma as illustratedin Figlinre 8.
